Technical Accounting for Business Combinations Under ASC 805

What makes us different?

Business combination accounting is one of the most technically demanding areas of US GAAP. ASC 805 requires acquirers to measure the fair value of consideration transferred, identify and fair-value all acquired assets and liabilities, recognize goodwill or a bargain purchase gain, and account for a range of deal-specific features — contingent consideration, indemnification assets, replacement equity awards, and pre-existing relationships — each of which requires careful analysis and documentation.

Corviniti provides technical accounting support for business combinations from the initial deal structure through the finalization of the acquisition accounting. We analyze the transaction, identify the accounting issues, prepare the technical documentation, and produce the journal entries and financial statement disclosures your auditors expect. We work alongside your internal team and coordinate directly with your external auditors to keep the process on schedule.

Our experience covers the full range of transaction structures — strategic acquisitions, private equity add-ons, SPAC mergers, asset acquisitions, common control transactions, and others. Each structure presents its own accounting questions, and we bring the technical depth to address them correctly.

We help with:
  • Acquisition vs. Asset Purchase Determination: Assess whether the transaction constitutes a business combination under ASC 805 or an asset acquisition, as the accounting differs significantly between the two.
  • Accounting Acquirer Determination: Analyze the transaction to identify the accounting acquirer, particularly in reverse acquisitions and SPAC mergers where the legal and accounting acquirer may differ.
  • Consideration Measurement: Measure the total consideration transferred at acquisition date fair value, including cash, equity instruments, contingent consideration, and assumed liabilities.
  • Purchase Price Allocation: Identify and fair-value all acquired assets and liabilities, including intangible assets not previously recognized on the target’s balance sheet.
  • Contingent Consideration Accounting: Assess the accounting treatment for earnouts and other contingent consideration — classification, initial measurement, and subsequent remeasurement.
  • Indemnification Assets: Account for indemnification arrangements where the seller provides protection against specific acquired liabilities.
  • Replacement Equity Awards: Assess the accounting for target employee equity awards replaced at acquisition, including the allocation between purchase consideration and post-combination expense.
  • Common Control Transactions: Analyze transactions between entities under common control, which are excluded from ASC 805 and require different accounting treatment.
  • Measurement Period Adjustments: Manage the measurement period process, including identification of new information that triggers adjustments to the preliminary PPA.
  • Acquisition Accounting Disclosures: Prepare the footnote disclosures required by ASC 805, including the description of the transaction, consideration transferred, recognized amounts, and goodwill.

Frequently Asked Questions

A business combination under ASC 805 occurs when an acquirer obtains control of a “business” — defined as an integrated set of activities and assets capable of being conducted and managed to provide a return. An asset acquisition is the purchase of assets that do not constitute a business. The accounting differs significantly: business combinations require fair value measurement of all acquired assets and liabilities and may result in goodwill recognition, while asset acquisitions allocate the purchase price to the acquired assets based on their relative fair values without goodwill.

The accounting acquirer is the entity that is deemed to have obtained control of the other in a business combination. In most transactions, the legal acquirer and the accounting acquirer are the same. However, in reverse acquisitions and SPAC mergers, the legal acquiree may be the accounting acquirer. This determination affects how the transaction is recorded — including which entity’s historical financial statements become those of the combined entity.

Contingent consideration — commonly structured as an earnout — is a component of the purchase price that depends on future events, typically the acquired company’s post-close financial performance. Under ASC 805, contingent consideration is recognized at fair value at the acquisition date. If classified as a liability, it is remeasured to fair value at each reporting period with changes recognized in earnings. If classified as equity, it is not remeasured. The classification and measurement of contingent consideration is one of the most judgment-intensive areas of acquisition accounting.

ASC 805 requires extensive disclosures about business combinations, including: the description of the transaction and the acquiree, the acquisition date, the consideration transferred, the amounts recognized for each class of acquired assets and liabilities, the amount of goodwill and the factors contributing to its recognition, the revenue and earnings of the acquiree since acquisition, and — for material acquisitions — supplemental pro forma information showing the combined entity’s results as if the acquisition had occurred at the beginning of the comparative period. We prepare all required disclosures as part of our acquisition accounting engagements.

The determination of whether a transaction is a business combination or an asset acquisition can be complex, particularly for acquisitions of early-stage companies or specific product lines. ASC 805 includes a “concentration test” that allows companies to conclude an acquisition is an asset acquisition if substantially all of the fair value of the gross assets acquired is concentrated in a single asset or group of similar assets. We analyze the transaction facts and prepare a technical memo documenting the conclusion.

A common control transaction occurs between entities that are ultimately controlled by the same party — for example, a parent company transferring a subsidiary to another subsidiary. ASC 805 explicitly excludes common control transactions from its scope. Instead, these transactions are typically recorded at historical cost rather than fair value, and no goodwill is recognized. The accounting treatment depends on whether the transaction is from the perspective of the receiving entity or the transferring entity, and we prepare a technical analysis to determine the correct approach.

Yes. We regularly work with foreign private issuers and companies with cross-border structures, including IFRS reporting, US GAAP reconciliations, and multi-entity consolidations for companies with domestic and international subsidiaries.

In most cases, we can begin within a few days of finalizing our agreement. Our onboarding process is straightforward — a brief discovery session, a clear statement of work, and secure access setup. We do not have lengthy intake procedures that delay the start of actual work.
